its a 3 fin third member so it is a 4cyl.

so i have two sets of 8" ring gears in the box, and only the rear will take that size, the other one needs to be a 7.5" right?

or i am all set? i really dont want to have the axles pulled out of the chunk and have that slow look of "awwww crap" come over my face.

thanks.
